IMPROVEMENT IN HEATING APPARATUS.

Specification forming part of Letters Patent No. 152,429, dated June 23,1874;. application filed Masr 21. 1874.

To all whom tt may concern Be it known that I, GUsTAvUs STEVENS, of EastTawas, in the county of Iosco and State ot' Michigan, have invented anew and Improved Heating Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing forming aA part of thisspecification, in which- Figure 1 is a vertical elevation, partly insection; Fig'. 2, aplan view with corner broken away.

The object of this invention' is to secure an economical method ofheating rooms without the'use of stoves or heaters, in which ordinaryfuel is burned; and it consists in a new and improved way of drawingpure air from .outdoors by means of a bellows operated by aclock-gearing, and of forcing it through airpipes heated by a large lampinto the room.

ln the drawings, A represents the box or casing of the apparatus. B is abellows,for which a blower may be substituted, having underneath theinwardly-opening valve a, which connects with the pipe that leads to theopen air. To `the upper arm of the bellows is attached a slanting arm,b, which is struck by the revolutions of a crank, c, and motion therebycommunicated to the bellows. Said crank c is attached to one of theshafts of ala-rgesized clockgearing, (l, having mainspring, arbor, andratchet-wheel, spring, pawl, spurgear, and ily. Leading from the bellowsis the flexible pipe or hose D, that conveys the air to theheating-tubes. E is an end door, to which a large lamp, F, is attachedby means of a bracket, and when this door is closed the flame from thelamp passes up a metallic pipe, G. Immediately around this pipe is woundthe coil H, through which the air is forced from the bellows, the end dbeing connected with the hose D. Surrounding pipe G and coil H is thecylinder I, which is made tight and filled with water or air, as may bedesirable, outside of this there boing still another cylinder, J, withair-holes c at the bottom.

The action of this heating apparatus is as follows: Vhen theclock-gearing is wound up by means of a key, the shaft is set in motionthat moves the crank c, and said crank, by striking the inclined arm b,gives to the bellows a motion that draws air from the outside and forcesit through the hose into the coil H, and afterward out into the room.Now, as the pipe G is heated directly Vby the fiame from the lamp, andthe coil H is in contact with it, and also immersed in the water whichsurrounds it, or the air, as the case may be, the air, in passingthrough said coil, must become heated before it passes into the room.The cylinder I also helps to heat the room byradiation, the heat beingconducted to it from pipe G by the water. Cylinder J is so arrangedas toallow the heated air from pipe G, coil H, and cylinder I to pass out atthe top, or to pass out at the holes c by putting on the cap K.

Having thus described my invention, what I claim as new is- Thecombination of the pipe G, coil H, cylinders I and J, lamp F,clock-gearing C, and blowing apparatus, for the purpose of heating andVentilating the room, by introducing pure air from outdoors, and heatingthe same in its passage through the apparatus before it enters the room,substantially as and for the purpose described.
